To all whom it may concern:

Be it known that I, HAAKON E. NoRBoM, a citizen of the United States, and resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Shaft- Hangers, of which the following is a specification.

Objects of the present invention are to provide a pressed metal shaft hanger which shall be comparatively light and inexpensive to make and yet possessed of the requisite mechanical strength, to provide a strong and reliable connection for holding the adjusting screws against deliection; and to provide a rigid connection for the lower cross bar.

To these and other ends hereinafter set forth the invention comprises the improvements to be presently described and finally claimed.

The nature, characteristic features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which- Figure 1, is a side elevational view illustrating so much of a hanger embodying features of the invention as is necessary for a description of the latter. Fig. 2, is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3, is a sectional View taken on the line 3--3 of Fig. 1, looking upward. Fig. 4, is a sectional view taken on the line le- 4 of Fig. 1. Fig. 5, is a side view drawn to an enlarged scale illustrating one of the parts detached. Fig. 6, is a partial plan view of the lower cross-bar. Fig. 7, is an end view of the same, and Fig. 8, is a partial top view of the hanger.

1, is a hollow curved leg of which there are two, although for the sake of clearness only one is shown in Fi 1, while hoth are indicated in Fig. 3. This hollow curved leg consists of a pressed sheet of metal, as steel. Each leg therefore is composed of a single piece bent to form a substantially closed form of box shaped girder, extending from the foot or top portion to the portion which supports the bearing, as will be described. rfhe hollow curved leg is laterally flanged at its top, as shown at 2 and intermediate of the flanges it is provided with a downward bulge a, having an oblong opening al for the passage of the means not shown by which the hanger is secured to place. The

leg is generally oblong in cross-section as shown in Fig. 3, and corrugated or ribbed at its upper outside portion 3, and flat at its lower outside portion 1. The meeting edges 5, are arranged on the inside portion of the leg. The meeting edges are provided with ears or parallel side wings 6, arranged about midway of the lengths of the legs and the meeting edges are also cut away or open as at 7 (Fig. 4), near the lower end of the leg for purposes to be presently described.

8, is a rectangular open ended trough shaped section or reinforcing plate consisting of a pressed metal sheet and it is arranged within the hollow leg opposite the open or cut away portion 7, thereof. This trough shaped section is provided with outward flanges 9 arranged in abutment with and secured to the inner faces of the front walls of the leg. The rear wall 10, of this trough shaped section is in abutment with the inner Hat wall il, of the leg (Fig. 1). The lateral adjusting screw 11, penetrates the abutting walls of the leg and trough shaped section and is engaged not only by a nut 12, arranged in the trough shaped section and held thereby against rotation, but also by a nut 13, arranged outside of the leg. These nuts and abutting walls insure a firm support and connection for the adjusting screw.

14E, is a. yoke plate having its ends fitted through and supported iii slots in the side walls of the trough shaped section. This plateis provided with an opening through which passes the shank of the connecting bolt 15, of which the head 16, is supported on the yoke plate in such a way that the side walls of the trough shaped section hold the bolt against rotation, thus the bolt is well and firmly supported and connected to the end of the leg.

17, is a pressed metal bottom piece, of generally boat shape. This boat shaped piece is provided at the under side of its ends with flat faced perforated bulges 18, for the connecting bolt 15 and its nut 20. The boat shaped piece 17, has at the upper part of its ends, deck like portions 21 upon which bear the ends of the legs 1. At the center part of the boat shaped piece 17, there are inturned lingers or flanges 22 and an open portion 23.

24, is an open ended trough shaped piece provided with lateral fianges 25. This trough shaped piece is fitted so as to rest on the flat bottom of the boat shaped part 17 with its flanges 25 in engagement with the inturned fingers l22.

26, is a carrier plate arranged cross-wise of the trough shaped piece 24e with its ends in notches formed in the side walls of the trough shaped piece. The vertical adjusting screw 27 engages a nut 23 beneath the boat shaped part 17 and also a nut 29 arranged above the carrier plate 26 and in the trough'shaped piece 2st, by which it is held against rotation.

The middle cross-bar or intermediate transverse brace comprises two pressed metal channel bars 30 and 31 attached at their ends to the ears 6, and each centrally bowed or bent. An inverted trough shaped section 32 is arranged between the bowed portions of the channel bars 30 and 31, the edges of this trough shaped section being flanged as at 33, so as to engage the bars. A bridge piece 34 is arranged cross-wise of the trough shaped section with its ends supported in notches or openings formed in the side walls of the trough shaped section. An adjusting `screw 35 passes through the wall of the trough shaped section 32 and through the bridge piece 34. There are nuts 36 and 37 arranged outside of the trough shaped section and of the bridge piece and they are engaged by the screw 35. The nut 37 is held against rotation between the side walls of the trough shaped section. The described arrangement of nuts for the adjusting screws gives the latter a good, firm bearing so that they are firmly held against lateral deflection.

The top cross-bar 38 comprises a plate of generally I-shape in plan having its center portion downwardly ribbed as at 39 and its end portions adapted to the lateral fianges at the top of the legs and provided with an oblong opening 40, for the bolts not shown and by means of which the hanger can be secured to place.

I-Iaving thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a pressed metal hanger the combination of a member provided with a space, a trough shaped part having notched walls .and arranged 'in said space, a supporting plate arranged in and held by said notched walls, and a screw penetrating said trough shaped part and nuts on said screw arranged to respectively abut on the trough shaped part and on the wall of the member, sulstantially as described.
